With few exceptions, cars with automatic transmissions should always be shifted into overdrive, as it allows the vehicle to shift into the highest gear available. While in a lower gear, the engine may work harder to maintain speed and use more fuel.
A:Removing scratches from a chrome surface entails applying polish to an extremely fine steel wool pad, then sanding the scratch from the surface. Use red jewelers rouge or a chrome polish for this project, as well as a soft cloth or #000 steel wool pad. Use this process only for light scratches on the surface of the chrome.
A:The front end of the car usually houses the vehicle's suspension, and squeaky noises are a sign that one of the components is failing. Some possible worn parts include shocks, struts, control arms, ball joints and bushings.
A:Hail damage can be corrected using a heat method, a specific hail repair kit or through the use of professional services. The heat and repair kits are at-home methods that are less likely to work than professional hail repair.
A:The buildup of pressure caused by adding too much coolant to a car can cause the rupturing of hoses, internal pipes and even the radiator. When coolant is added to a car, it is cold, however, while the engine is running, the liquid starts to expand, causing a buildup of pressure. If the radiator is too full, this buildup of pressure is often too great for the internal workings of the car.
A:The dashboard symbol with an exclamation point in the cutaway of a tire is the tire pressure monitoring system indicator. This dashboard symbol signals that one or more tires is low on air, or that the system needs resetting — especially if the tires have been serviced recently.
A:Coolant leaks and engine overheating are usually caused by a failing water pump. Automotive water pumps are designed to leak coolant through weep ports as a warning that they are failing. Aside from overheating, a distinctive grinding or whining noise caused by a bad bearing is also a symptom of a bad pump.
A:Depending on whether the engine is hot or cold, there are a couple different reasons why a car might start with no problem but stall shortly afterwards. If the problem only happens when the engine is cold, a bad electric sensor is likely to blame. If the car stalls even when the engine is warm, the cause is likely a faulty electric fuel pump.
A:Some of the most common causes for a car's stalling whilst driving include: a poor idle speed control, or ISC, system, low fuel pressure, loss of ignition and vacuum or EGR leaks. Diagnosing the specific problem should be a priority in order to get it fixed.
A:Most moving parts of an engine expand when it overheats, and they can warp, bend or even break if the car is driven in this condition. A few examples include damaged cylinder walls, bent connecting rods, damaged bearings, broken crankshafts, warped cylinder heads and damaged head gaskets, all of which require expensive repairs.
A:There are multiple ways to make a car faster, such as the installation of a new exhaust system, according to CarsDirect. New exhaust systems also make cars louder, but such alterations are not always legal, explains the Criminal Justice Degrees Guide.
A:The best rule of thumb when it comes to determining when to dim high beams is that a driver should turn headlights to low when he sees another car's headlights, either in the rear view mirror or coming toward him. Laws regarding the matter vary by state.
A:The check gauges light on a vehicle indicates that a malfunction has occurred and the vehicle needs to be inspected, serviced or repaired. A check engine or check gauges light can indicate a loose fuel cap, low engine oil, an overheated engine temperature or a malfunction in the engine or electrical system.
A:The airbag light comes on when the backup battery is drained or damage has occurred to the clock spring or the airbag module. Because the light can have many causes, a technician must diagnose the problem if the light stays on.
A:Critical symptoms of a weak car battery include difficulty in starting the vehicle, a check engine light turning on, a low fluid level, corrosion on the posts and a swollen battery case. Age affects battery performance as well.
A:According to Progressive, the best types of hail protector for a car are personal covered parking ports, temporary shelter such as mall parking garages, and car covers or blankets. Temporary shelters, such as mall parking garages, are useful for waiting out storms to avoid vehicular damage.
A:A car that starts up initially but dies immediately thereafter is experiencing a problem with either its carburetor or fuel injection system. The culprit depends on the year, make and model of the vehicle in question. Carburetors are easy to fix, while fuel injection issues cost a large sum to diagnose and repair.
A:A complete car tune-up includes spark plug replacement, rotor replacement, fuel injector cleaning, a new air filter, a new fuel filter, a new PCV valve and checks on various systems, including fluid levels, ignition, emissions, manifold intake, compression, timing, idle, distributor cap, battery, choke, vehicle computer, belts and safety. Anything that shows wear and tear should be replaced during a tune-up.
A:A knock sensor detects engine knock or detonation, which then controls the timing of the engine. Engine knock and detonation are usually harmful engine vibrations that are often caused when a spark plug does not ignite the fuel properly. This will cause the engine to run roughly, and may cause serious damage if not taken care of immediately.
